notrub Posted March 19 Report Share Posted March 19 The test sheet from WarringtonFire for a door indicates use of a certifire approved latch, max case dimensions 19x15x64mm with a forend 57x26 and keep 57 x 24 and there is no tolerance specified. I've been completely unable to find anything that complies with this - typically it's the case that's either too high or wide. I've been in contact with WF but they can't help. I've looked at at least 10 different manufacturers now that provide specs online but unable to find one to these specs that is Certifire approved. Closest I've found is 21x15.5x64.5 How critical are these measurements? Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted March 21 Report Share Posted March 21 Contact the door leaf manufacturer's technical department, via the UK agent/distributor (if necessary). They should be able to advise. Quote Link to comment Share on other sites More sharing options...
